So far in BG3 Arcana, Religion, History and Investigation has come up I think.
The fact that it has come up doesent make it worth taking over other things. More often that not you succesfully gain information through other means, which involve talking and spellcasting, and other stats have more to offer, wisdom is used to resist things as hold person and shake off mind affecting spells etc.
The only use in normal dnd games were RP reasons, to play as 'smart' character, here it doesent matter at all, you dont get affected if, say, your int was 2, you would barley notice it (unless youre a wizard).
